Water heater "Delimano": customer reviews. Instant instant water heater "Delimano" instantaneous: reviews

For a long time now, everyone can’t imagine their life without hot water. Therefore, its absence for any reason is perceived as a tragedy. The feeling of discomfort forces you to look for ways to solve the problem. Some heat water in the kitchen with pots, others attach a plastic bottle to the kitchen faucet and pour warm water from the kettle into it. But it turns out that everything has already been invented without us. Water heaters will help provide the desired level of comfort. One of them is “Delimano” - instantaneous water heater.

Types of heaters

Flow-through

They heat water without using a storage tank. The water in it heats up immediately after turning on the tap. Gas or electricity is used to heat water.

Electrical

Inside such a device there is a heating element - a tubular electric heater. Water, in contact with the heating element, heats up.

The temperature is regulated by increasing or decreasing the water flow or using the heating element power regulator. The smaller the stream of water flows from the tap, the more the remaining part heats up. Therefore, the thinner the stream of water, the hotter it is. This type includes electric instantaneous water heaters "Delimano". Reviews about them are mostly positive.

It is possible to have both control systems in one model. These devices are more expensive.

Cheap water heaters do not have control devices, so the temperature in them is adjusted using a cold water tap.

Gas

They are easy to use, but difficult to install. To install them, you need ventilation through which gas combustion products will be removed from the house. It is necessary to coordinate with the relevant authorities all issues regarding installation, ventilation, and safety. After all, gas can explode and you can be poisoned by it. In addition, gas heaters do not turn on when the water pressure is low. But if gas is cheaper than electricity, then appliances are more economical.

Cumulative

They're boilers. They consist of an element that heats water, a storage tank (tank) and devices that perform additional functions. Are divided into:

electrical;
gas.

The advantage of gas storage heaters is the ability to quickly heat large quantities of water. But the device itself is quite expensive.

Electric storage heaters are cheaper, but they consume a lot of energy and take a long time to heat water. If you need to wash a large family, this process can take a whole day.

Design and operating principle of Delimano

The Delimano water heater does not differ in appearance from conventional faucets, but a heating element is installed inside, passing through which the water is heated.

The device consists of the following parts:

housing made of heat-resistant plastic;
Heating element with a power of 3 kW;
a pressure valve that regulates the water supply to the heater tank;
control lever;
indicator lamp;
wires

This rather simple design not only facilitates further maintenance and repair of the device, but also significantly reduces its cost. Buying a Delimano water heater will cost you much less than a regular electric tank.

The principle of operation of the device is as follows: when the control knob is turned to the hot water position, cold water, with its pressure, opens the valve and fills the tank where the heating element is located; at the same time the heating element turns on. Hot water flows out through the tap, and cold water heats up as it enters the device’s reservoir.

Methods of operation of heaters: non-pressure

They have a power of up to 8 kW. Suitable for the dacha. The inlet valve protects the system from water pressure. After all, heating in a non-pressure heater is carried out at atmospheric pressure. There is no tap at the outlet. The heater is designed for showering. For this he has a special nozzle. Does not require special wiring. Easy to install and operate.

Instant digital with display

Unlike the standard model, this device has a digital display instead of an indicator. As a result, it is much more convenient to monitor the heating temperature of the water, which makes its operation safer, especially for children. The device and principle of operation are similar.

The body, like a standard water heater, is made of white heat-resistant plastic, but the faucet is made a little longer and in a different, more luxurious style with metal parts. The crane can rotate 360°.

Pressure flow electric heater

It has no attachments. It consists of inlet and outlet taps, with the help of which it is connected to the water supply. Such devices include the “Delimano” water heater faucet. Reviews indicate that the undoubted advantage of this kind of heaters is the ability to connect them to several faucets, which allows you to use it simultaneously in the kitchen and bathroom. The switching on of such heaters is automated. They are single-phase and three-phase. The former consume 3-12 kW, the latter – 3-30 kW. They have an electronic system for regulating and maintaining water temperature. The device is usually placed under the washbasin. Disadvantages: high price, energy consumption.

Device Specifications

The water heater has the following parameters:

rated power - 3 kW;
operating voltage - 220 V;
dimensions - 12.5x7x7 cm;
weight - 1 kg;
case material - plastic;
maximum heating temperature - +60 °C;
type of device - flow-through.

The manufacturer has provided a short power cable (1 m), so when connecting you have to install a separate outlet next to the bathtub or sink and use an extension cord.

The inlet diameter is 21.8 mm, which coincides with standard plumbing parameters. The device can be connected with a simple faucet hose.

The heater becomes a replacement for the faucet; these devices cannot be installed together.

When installing, pay attention to the high power of the device. Reinforced wiring is not required, but outdated communications may not withstand such a high load.

Instantaneous water heater in the bathroom.

Flaws

But when operating, powerful water heaters consume a significant amount of energy. That's why they are not very profitable. An inexpensive heater does not heat water well, so drawing a bath of hot water with its help will be problematic.

High power heaters require a separate supply of electricity to the device. Otherwise, the electrical wiring may not be able to withstand it, or the device that monitors the load on the network will turn it off throughout the apartment.

This must be taken into account when buying a Delimano instant water heater. Customer reviews indicate that not everyone can do this work. If the stove in the house is powered by electricity, then the wiring is designed for heavy loads and will withstand them.

Justified fears

Installation method As can be seen from the technical characteristics, the Chinese manufacturer offers consumers a fairly simple and compact device.
Inside it there is a powerful electric heating element, through which cold water passes in a flowing manner and heats up in a very short time. The small size of the installation raises doubts among many users. Is the device's power sufficient to produce the stated temperature? Practice has shown that 3 kW is quite enough to get the expected result. But it is worth considering that by turning off the hot water meter, we will force the electric meter to work with furious force. And here you have to choose the lesser of two evils.

Another concern expressed by users on the forums is the safety of using the installation. Current and water are two enemies, not allies. Is it safe to use the described device? In this regard, as the manufacturer assures, there is no need to worry. After all, the delimano flow-through faucet has good insulating characteristics. The body is made of plastic, which is known to not conduct electricity. Strong gaskets are installed inside it, and the design of the heating element is thought out in such a way that there are no dangerous technical components.

"Delimano" - instantaneous water heater

An electric faucet attachment is designed to heat running water.

When you need a Delimano water heater:

If there is no hot water or it is turned off for a long time.
To save money. Although electricity is not cheap, Delimano heats water immediately before use and exactly as much as needed.
At the dacha, a Delimano water heater will come in handy. Reviews say that it is most appropriate there.
If there are no other sources of water heating.

Purpose of the crane

Many, having seen the new product described, wonder why a delimano flow-through electric faucet is needed. So let’s outline the scope of its application. A compact water heater is useful when hot water is turned off in city apartments.

Features of Portable Electric Water Heater

It is convenient to use it at dachas, where people visit and dream of familiar amenities, without worrying about installing capital stationary utilities. Using such a nozzle, you can wash dishes, fill the bathtub, that is, use hot water for its intended purpose. The device produces well-heated water instantly. At the same time, its temperature is easy to regulate, so using the tap is extremely simple.
On the forum, many users note that the delimano electric flow faucet helps out when moving into a new apartment that is still undergoing renovation. With its help, you can organize quite comfortable conditions where engineering communications have not yet been fully connected.
Another important point is saving on bills for housing and communal services. If your apartment has a hot water meter installed, the delimano flow-through tap will allow you to refuse to use the central hot water supply and pay only for electricity consumption. You can install it in your apartment or house yourself, without resorting to the help of plumbers and without informing the housing and communal services authorities.

Note! The nozzle does not take up much space like electric storage boilers. With its help you can save your family budget. The device comes with instructions that detail how to remove the old mixer and install a delimano flow-through faucet in its place.

Despite the high power indicated in the technical data sheet of the product, the described device consumes much less energy than a storage electric boiler. At the same time, the manufacturer assures that the efficiency of his invention is greater than that of stationary installations. The water heats up much faster, the device is more convenient to use, and once you buy such a nozzle, you can forget about problems with hot water forever.

"Delimano" nozzle device

In appearance it differs little from a regular faucet. The electrical cord is located at the back of the heater, so it is practically invisible. On the right side there is a tap with which the water temperature is regulated.

There is a water heating indicator on the front of the faucet. By looking at it, you can find out to what temperature her Delimano instantaneous water heater heated her. Reviews indicate that doing this is convenient and fast.

Difference by type of control

Flow heaters are distinguished by the type of control, which is based on hydraulics or electronics.

Hydraulic control type

Hydraulic control is typical for cheap domestic water heaters. A design feature of the flow-through heater is the presence of a block consisting of a membrane and a rod. When the water tap is opened and closed, the mechanism is activated. The rod actuates the switch, thereby starting or stopping the water supply.

A hydraulic unit with two stages is considered improved, each of which has its own pressure of the passing fluid flow. When the flow is low, the first stage is switched on. As the pressure of the moving fluid increases, the unit switches to the second stage.

Single-stage instantaneous water heaters are equipped with a heating element with a power of up to 6 kW. If the liquid flow is weak, the heater does not turn on, which is a huge drawback.

The hydraulic control unit is not able to accurately maintain the set water temperature for a long time. The downside is the lack of protection against air penetration to the heating element. Flow-through water heating devices with a hydraulic control system are connected to only one water supply point. Otherwise, there is a risk of temperature fluctuations, which are most dangerous for 9 kW heaters.

Electronic control type

Electronic control is carried out by sensors sending a signal to the processor. All parameters are adjusted automatically. Sensors monitor temperature, pressure and water pressure. Electronically controlled instantaneous water heaters come in two types:

models with only water temperature control;
models with adjustable temperature and liquid pressure.

Electronic control allows the use of an instantaneous electric water heater with several water dispensing points. The disadvantage is that the electronic unit is expensive, but it rarely fails.

Why is the Delimano water heater convenient?

Reviews indicate a number of advantages of the device:

Small size: width - 12.5 cm, height - 7 cm.
The device is quite light, its weight is 772 g. This makes it possible to easily transport it from home to dacha and vice versa.
You don't need a tank to use it.
The faucet does not have any additional buttons, knobs, or scales.
Easy to assemble and disassemble.
The water heats up quickly.
An electric heater is inexpensive.
The standard-shaped coil allows for easy installation of the system.
Beautiful appearance
Water passing through the heater does not lose its taste.

Ease of use encourages customers to purchase the Delimano instant water heater. Reviews indicate that most users did not experience any problems when installing the nozzle on a running water tap. The device saves energy. This happens due to the fact that it heats only the amount of water that is needed. And if you heat it with an electric boiler, then the whole tank of water will be hot, no matter how much you use. The remaining water will simply cool down and it turns out that the electricity was wasted.

The water does not stagnate, as can happen when using a storage water heater.

Universal. Can be put on any tap where there is water and electricity. Installs easily and does not require special preparation. You can periodically move it from home to the country or to the office, from the kitchen to the bathroom.

Main types of breakdowns and how to fix them

When using a faucet heater, users encounter the following problems:

The red indicator light does not light up and the water does not heat up when the handle is turned to the hot water supply position. There is no electricity or the water pressure is too low. It is worth checking the power cable, making sure that the power wire is connected correctly, and making sure that the pressure is at least 0.04 mPa.
The red indicator light is on and the water is cold. The problem is increased water consumption. It is necessary to adjust the position of the hot water supply knob and reduce the flow rate.
The water is hot, although the pressure is weak. You should disassemble the product and check whether deposits have appeared on the water filter and fluid outlet holes, and if so, clean them.
The indicator light lights up, but the water does not heat up. This indicates a breakdown of the heating element. It is worth contacting the service center.

The warranty on the product is 1 year, including for self-installation, and on the case – 5 years. During this time, in case of breakdowns, you can contact the service center. They are required to carry out free diagnostics and, if necessary, repair or replace the device.

How does the electric water heater “Delimano” differ from other instantaneous heaters?

Delimano KDR-4E-3 is the most popular model. It is produced by the Slovenian company Studio Moderna. In just a few seconds the water temperature rises to 60 degrees. Easy to install. Has a stylish look. Quite powerful, 3 kW, but in general it consumes little energy because it only heats the required amount of water. This is the benefit of the Delimano water heater. Customer reviews indicate that the electricity bill increases slightly when using the device.

Water pressure is within 0.04-0.06 MPa. IP×4 protection allows you to reliably insulate all electrical wires and connections. When you open the tap, the water immediately begins to heat up. That’s why it is also called the “Delimano” instant water heater. Reviews confirm that hot water appears very quickly. It is convenient to regulate its temperature. The weaker the stream, the hotter it is. The LED power indicator allows you to monitor the operation of the nozzle.

The electric heating device is protected against electric shock and voltage surges, which shorten the service life of the nozzle. A special sensor turns off the voltage if the water pressure in the system and the temperature at the outlet exceed a specified interval. The device will turn on itself and begin to heat the water after the parameters for which the Delimano water heater is designed are normalized. Reviews indicate that due to the lack of filters in the nozzle, the water flows is not very clean, so the tap becomes clogged.

How to choose the right model

A instantaneous water heater is a device that works simultaneously with water and electricity. Therefore, when choosing, you should pay attention not so much to the design and color of the device, but to safety. The main criteria are as follows:

RCD. This is a built-in protective shutdown device, the presence of which is mandatory on the water heater tap. It eliminates the threat of electric shock to a person. An RCD will also prevent breakdowns of the product itself during voltage surges in the network.
Protection against liquid overheating. A built-in sensor is required that turns off the electricity at a temperature of 60 degrees. When it drops, the power turns on automatically.
Protection against dry inclusions. When the water is turned off or at a minimum pressure of 0.4 mPa, a special sensor will not allow the power to turn on. Also, the device will operate under excessive pressure in the water supply.
Protective device against water hammer. They can damage even high-quality heater taps. The device consists of a silicone damper and a plastic element hidden inside the body of the product.
Protection of wires and the device itself with sealed sheaths that prevent moisture penetration. They are manufactured in accordance with international quality standards.

The Delimano device is equipped with the listed sensors and functions and is therefore safe to use. Both models work on the same principle and have similar parameters. However, reviews of the Delimano water heating tap show that it is more convenient to use a product with a digital display that displays the water temperature. In addition, this makes the device safe to use, which is especially important in a home with small children. At the same time, the standard model is cheaper - it is simpler in design, but in terms of the main parameters it is no different.

Advantages and disadvantages

Among the positive qualities of this device are:

Compact size compared to a boiler or geyser.
Saves energy on washing dishes, because the device turns on only when the handle on the tap is turned. The power of the heating element is 3 kW, not much more than that of a boiler of 2 kW.
Easy to install, each user can install it themselves without resorting to the services of specialists.
Quite good protection, the device will not turn on if the pressure in the network is less than 0.4 atm, and if there are large voltage drops in the electrical network.

It is worth mentioning several negative points that consumers express in their reviews:

According to installation rules, an electric water heater must be grounded. Therefore, in most cases, if it is not available, you have to contact specialists for its installation.
The Delimano water heater is not designed to heat large quantities of water. This is a kitchen option for washing dishes and therefore you most likely won’t be able to take a shower.
Quite a significant price.

However, all these disadvantages are offset by the convenience that a person receives from using a Delimano water heater.

Advantages and disadvantages

An instantaneous electric water heater on a faucet is usually compared to a boiler, and an instant water heating faucet has quite a few advantages.

Heats water in an unlimited volume - as much as the consumer needs for his needs. The boiler has a specific volume; if there is not enough warm water, you need to wait for the next batch to heat up.
The second advantage also leads to the third - the rate of supply of warm water is higher than that of a boiler.
A faucet with a water heater does not take up much space, unlike storage systems.
The water has a constant temperature, it does not overheat, saving energy. It is possible to further regulate its temperature if necessary.
Water is heated by volume exactly as needed. There may be excess in the boiler, the heating of which was spent on electricity. And the central supply of hot water inevitably spends a large amount of energy on heating water, part of which simply cools down in the systems, waiting to be used.
The device has a lower cost compared to storage systems.

There are also disadvantages:

Due to their small dimensions, some designs do not have filters. The longevity of the water heater will depend on the quality of the water in the water supply network.
A faucet with a water heater consumes a relatively large amount of electricity.
There is a limitation on the water heating temperature; if there is a need for water hotter than 60° or 65°, then this will not work.
Due to its power, an electric heater in a faucet requires careful attention to the wiring in the house.
When describing instantaneous electric water heaters for taps, reviews often contain information that the performance of the tap is not very high and the heating temperature may be not 60, but 40 degrees.

Tip: Before choosing a device, you should evaluate whether the internal electrical network is ready for additional load. If not, do the work: replace the outdated wiring or make a separate one for the electrical appliance.

Why a Delimano water heater faucet?

Heats water to 60 degrees within 5 seconds.
Looks much more attractive than a regular faucet in the kitchen or bathroom.
Does not require complicated installation - you can easily install it yourself.
Takes up much less space than conventional boilers and storage water heaters.
Significantly saves energy compared to conventional heaters.
